  • Danger of cancer

    1. 1. CANCERThe prevention is in you!
    2. 2. According to the National Center for Health Statistics, cancer causes roughly23 percent of all deaths in the US. It is the second leading cause of death andthe leading cause of death in children ages one to 14 in our country.In 2010 there were reportedly 1.5 million new cases of cancer diagnosed inAmerica and approximately 570,000 died from cancer in that same year.Cancer will effect about three out of four families in the United States. Thatmeans that one in every two men and one of every three women will developcancer.Research predicts that in the very near future cancer will be the number onecause of death in the world.About 60 to 80 percent of all cancers can be prevented. All it takes is to beaware of your risks and follow the simple recommendations to preventcancer.Here are the facts:References: textbook pages 367 and 391

    4. 4. CANCER IS AN UNCONTROLLED GROWTHAND SPREAD OF ABNORMAL CELLSThe picture on the left showswhat normal and cancer cellslook like under a microscope.As you can see normal cellsare round and only have onenucleus where as cancer cellshave multiple nuclei and losttheir nice round shape.Reference: Textbook page 365Photo credits: www.visualsonline.cancer.gov/
    5. 5. Deoxyribonucleic acid or DNAand ribonucleic acid (RNA)controls the growth of cells.When the nuclei loses the abilityto control cell growth andregulation, mutant cells start todevelop and cell division isdisrupted.This is when cells can start togrow out of control anduncharacteristically, formingwhat is called a tumor.A tumor is a mass of cells thatcan either be benign(noncancerous) or malignant(cancerous).References: textbook page 365Photo credits: www.healthspablog.org/
    6. 6. There are tumor suppressor genes within the DNA and when thereare defects in these genes, DNA starts to alter. That is when cancerstarts to form. These defects can come from many different causesexternal and internal. The then defective DNA divides and mutatesuntil a malignant tumor is made. These tumors make anenzyme, known as Telomerase that seems to keep the cancer cellsfrom dying.Reference: Textbook page 365-366Photo Credits: www.drdavesbest.com
    7. 7. HERE IS A PICTURE OF SOMECAUSES OF CANCERSThere are outside causes like UV-rays and those that can come fromour diet (internal) that we cancontrol by avoiding excess sunexposure and eating a healthy diet. Reference: Textbook page 374Photo Credits: www.cisncancer.org
    8. 8. CANCER ALL BEGINS WITH THE ABNORMALGROWTH OF ONE CELLOnce that begins that onecell can multiply intobillions and billions ofcancer cells. At this pointthe malignant tumor hasbeen confined to one areaand has not spread. Thisstage is known ascarcinoma in situ. It is notreat to the health of thehuman, but once oxygenand other nutrients enterthe cells that is whengrowth and the spread ofthe cancer occurs. Reference: textbook page 366Photo Credits: www.web-books.com
    9. 9. AFTER SOME TIME THE CANCER CELLS PRODUCECHEMICALS THAT INCREASE THE FORMATION OFBLOOD VESSELS INTO THE MALIGNANT TUMORWhen the formation ofangiogenesis (blood vessels)occurs, the cancer cells cannow break from the tumorand spread to the rest of thebody. The process of themoment of cells from one partof the human body to anotheris called metastasis. Whencancer cells metastasize, it candevelop in other parts of thebody causing the treatment ofthe metastasized cells harderto cure.Reference: Textbook page 366-367Photo Credits: www.iayork.com/

    11. 11. ONE OF THE MOST COMMON TYPES OF CANCERIS LUNG CANCERPhoto Credits: www.karunaflame.com/
    12. 12. LUNG CANCERRISKS1. Smoking cigarettes, cigars, and pipes increase the risk ofcancer. A study shows that about 9 out of 10 tobacco smokerscases get lung cancer.2. The length and the amount of times a person smokes increasestheir risk of lung cancer. The more a person smokes per dayrises their risk significantly as well as the number of years aperson has been smoking.3. A nonsmoker who lives with a smoker has a 20 percent greaterrisk of getting lung cancer than living with nonsmokerroommates.4. The exposer to radon gas, which is greater in homes ofsmokers.Reference: Textbook page 377
    13. 13. Smoking is a huge risk for lung cancer. Did you knowthat smoking can cause other cancers and diseases?Photo Credits: www.cdc.gov/
    14. 14. WARNING SIGNSTHAT IT MIGHTBE LUNG CANCER1. Any unexplained/out of the ordinary symptoms that were notpresent before like constant diarrhea and extreme weightlose without trying.2. Coughing up blood.3. A persistent cough.4. Feeling short of breath.5. Constant pain in chest and back.6. Reoccurring Bronchitis and/or Pneumonia.7. Abnormal fatigue.References: Textbook page 379

    16. 16. FACTORS THAT CANLEAD TO PREVENTIONOF LUNG CANCER1. STOP smoking now! A person with ten years of not smoking afterquitting reaches the same health as a person who has neversmoked.2. If you don’t smoke, NEVER start. It is a hard and harmful habit toquite.3. Get your home or dorm tested for radon gas. They should betested periodically for the gas.4. Exercise you right for clean air. Go where there is not chance forsecondhand smoke.5. Get regular exercise. Exercising increases a person’s lung and bodyhealth.Reference: Textbook pages 376-377Photo Credits: www.smokeforwhat.com

    18. 18. Stop smoking now (if you do) and don’t start (if youdon’t).Get plenty of exercise, at least three times a week.Eat a healthy balanced diet.Limit your exposer to sun to the recommendedamount (10 to 20 minutes of unprotected sunexposer).Schedule a cancer screening with your doctortoday!Prevent cancer now by:Reference: textbook page 374
